Hello,
I am trying to learn SML, but drowning in its streams.

The following function does what I want in SML/NJ, but not in PolySML.
Is the function wrong, but SML/NJ lenient and PolySML not?  
If the function is wrong, what is the best way to get
input from stdin without a newline? 

fun askName () =
let 
  val a = TextIO.inputLine TextIO.stdIn
  val b = String.translate (fn x => case x of #"\n" => ""|_ => str(x))
in
  case a of
     SOME("\n")    =>  NONE
  |  SOME(s) =>  SOME (b s)
  |  NONE    =>  NONE
end


Thanks
Johan
